SEEDER.

SPECIFICATION formingpart of Letters Patent No.- 274,460, dated March27, 1883.

' Application filed August 14, 1882. (ModeL) To all whom it may concern:

Be it known that I, ROBERT S. CARR, of Hamilton, Butler county, Ohio,have invented certain new and useful Improvements in Seed ers, of whichthe following is a specification.

This invention relates to that class of seeders formed of a rotaryseed-wheel inclosed in a seed-cup to which grain is admitted from ahopper, a series of the devices being generally arranged in one row upona single actuatingshaft under a single hopper to form the wellknowngrain-drill.

My invention consists of certain novelties of structure hereinafterspecified.

Is In the accompanying drawings, Figure 1 is an elevation ofthedischarge side of the device; Fig. 2, a face view of the seed-wheel,

and Fig. 3 a vertical section of the device drawn transverse to theshaft.

A is the seed-cup, whose general form is as usual. B is one of the sidewalls of the cup;

0, the opposite sidewall; D, a disk fitted to revolve in the side wall 05 E, a bearing-boss upon the side wall B; F, the usual cup-shaft,

in this case shown as a round shaft; Gr, an

apron at the top of the cup, reaching from one side wall to the other;H, a segmental gate cast to wall B and reaching across the cup to theinner face of disk D; 1, the usual diso charge-weir; J a disk fastenedto the shaft F; K, round pins fixed in disk J, and projecting throughholes in disk D into the seedcup; L, the hub projecting outward fromdisk J; M, a pin-hole through huh L and shaft F to receive anattaching-pin; N, a mortise from inner face of disk J to pin-hole M, thehole M forming the bottom of the mortise; O, a gate fitted to slidethrough wall 13 into the cup and close the space between the bottom edgeof 40 segmental gate H and the bottom of the seed cup; P, a stem to gate0, extending through wall 0; Q, a notched head on stem P, grasping theperiphery of disk J; R, a notch in the inner end of gate 0; S, a bearingin the hot- 5 tom of the cup, in which slides the stem 1?; 'l, the usualrivet for attaching the two parts B G of the cup together.

The shaft F is arranged to slide longitudinally through the cup, asusual, and the usual adjusting mechanism may be employed to effeet themotion. When the shaft is adjusted cndwise the pins K become projectedmore or less into the seed-cup. The gate 0 follows such movement of theshaft and feed-pins and closes so much of the space under the segmentalgate H as is not required for the passage of the pins as they rovolve inthe direction indicated by the arrow in Fig. 3. These pins carry thegrain through the space between the end of the gate 0 and the side wall0 toward the discharge I. The notch It in the inner end of the gate 0permits the end of the gate to contact with the disk -D, and thus limitthe further withdrawal of the pins K before the pins are so farwithdrawn as to endanger their being withdrawn from the disk D entirely.The grain in the cup has free access to the entire surface of the pins,and the pins must be ofa round or other non-cutting section to preventdamage to the grain. The 0 apron G, extending, as it does, well backinto the seed-cup, prevents theleakageoi' grain over the top of thesegmental gate H.

The arrangement of stem 1? to engage the disk J and move the gate 0yields an eliicient 7 and simple structure but, if desired, the gate 0may be operated from the shaft by other means.

Then the disk J is cast the mortise N is formed without asepcrate core,and this mor- 8o tise naturally forms between its bottom and the sideface of disk J the pin-hole M, thus saving the labor of drilling thishole through the hub L.

\Vhile I show a round shaft F, a square one may be used withoutinvolving any modifications of any part of the device not within therange of mechanical skill.

I do not claim, broadly, a feedwhccl formed ofpius projecting through adisk into the seede cup; nor do I claim, broadly, the combination ofsuch form of seed-wheel with gates to close the front of the seed-cup.

I claim as my invention- 1. The combination, substantially as set 5forth, of seed-cupA, having apron G, disk D, shaft F, feed-wheel J K,segmental gate H, and gate O.

2. The combination, substantially as set 4. The combination,substantially as set forth, of seed-cup A, having apron G and forth, ofshaft F, feed-wheel J K, having hub 10 segmental gate H, disk D, shaftF, feed-wheel L, and mortise N M.

J K, and gate 0, having stem P and head Q.

5 3. The combination, substantially as set ROBERT CARR forth, 'ofseed-cup A, having apron G and Witnesses: segmental gate H, disk D,shaft F, feed-wheel J. W. SEE,

J K, and gate 0, having notch It. JOHN LORENZ.
